Refine your ability to see things that usually are unseen.
Detect invis is available to:
Mages : level 2. Any Alignment.
- This spell lets you see invis items, mobs, and players. It is level-based, however, so a spell cast by a higher level mage will see a higher level invis than that of a lower level mage. It is also possible to "pump" this spell to make it more effective. For example, pumping 200 mana into this spell can be done with the following syntax: c 200 'detect invis'. A normal cast of this spell at level 30 mage costs 5 mana.
